Wrote bad checks 2 years ago or longer can he still present to the prosecutor or just collect through garnishments?
Sounds like a first-degree misdemeanor, which would be a two-year statute of limitations under Ohio law. If you receive a summons in the mail or are arrested, you should hire a criminal defense attorney who can draft a good motion to dismiss on statute of limitations grounds.
Handling the case on your own might sound like a good idea, but you could accidentally waive the issue and then you could possibly end up convicted of a crime even though the statute of limitations expired. Hire a professional to help you fight the case immediately.
